Answer 2

Answer:

The correct answer is Option $4 : 373K$

Step-by-step explanation:

When gypsum ($CaSO_4.2H_2O$) is heated to a temperature of $100^0C (373K)$, it loses three-fourths of its water of crystallization and forms plaster of Paris ($CaSO_4.\frac{1}{2} H_2O$)

Plaster of Paris :

Plaster of Paris is a quick-setting gypsum plaster made of calcium sulphate hemihydrate, a fine white powder that hardens when moistened and left to dry.

Plaster of Paris, which has been around since antiquity, gets its name from the plentiful gypsum that can be found nearby Paris.
